Performance and Technology
Powerful Engine: The Cat C4.4 engine meets U.S. EPA Tier 3 and EU Stage IIIA equivalent emissions standards, offering reliable, quiet, and durable power.
Gradeability: Theoretical gradeability is 55% for the CS10 GC and CS11 GC, and 50% for the CS12 GC.
Cat COMPACT Technology: A suite of technologies for consistent, uniform, and efficient compaction:
- Machine Drive Power (MDP): Measures energy to overcome rolling resistance to indicate soil stiffness (30-60 cm deep).
- Compaction Meter Value (CMV): Utilizes a drum-mounted accelerometer to indicate soil stiffness of multiple aggregate layers (up to 1.2 m deep).
- GNSS Mapping: Correlates compaction data with GPS for real-time maps to visualize progress and identify efficiencies.
- Machine-to-Machine Communication: Helps keep rolling patterns in sync by sharing data between machines.
An operator is shown using a tablet or screen displaying data related to Cat COMPACT technology. Text explains Cat COMPACT as a suite of technologies for consistent compaction, detailing MDP, CMV, GNSS Mapping, and Machine-to-Machine Communication.
Cat LINK Technology: Telematics for managing equipment and job sites:
- Product Link™: Tracks location and hours, streamlines diagnostics and maintenance scheduling.
- VisionLink®: Access product data anytime, anywhere for informed decisions.
- Cat App: Delivers machine data to smartphones or tablets for easy access and smart decision-making.

Maintenance
Easy-Access Maintenance: Daily inspections are simplified with grouped checkpoints and components within easy reach. The one-piece hood tilts forward for exceptional access to the engine and cooling system. S·O·SSM ports are provided for simple oil sampling.
Extended Maintenance Intervals: Industry-leading intervals include:
- 12,000 hr coolant change
- 3,000 hr hydraulic oil change
- 3,000 hr vibration bearing oil check
- 500 hr engine oil and filter
Maintenance-Free Hitch: The articulation hitch requires no greasing.

Options and Specifications
Expand Performance: Options enhance productivity, safety, and stability.
- Shell Kit Option: Oval-faced pad design for superior thick-lift compaction, or square-faced pad design for thin-lift compaction and surface sealing.
- Optional XT Weight Kit: Adds weight to upgrade CS10 GC to over 11 metric tonnes and CS11 GC to over 12 metric tonnes, providing higher static linear loads for wider applications.
- Operator Station Options: ISO mounted sun canopy, ROPS/FOPS canopy, or ROPS/FOPS cab for operator comfort and protection.
